Module Astlib.Ast_metadataSource
Meta data related interface for a ppx rewriter
val add_ppx_context_str :
tool_name:string ->
Parsetree.structure_item list ->
Parsetree.structure_item listExtract information from the current environment and encode it into an attribute which is prepended to the list of structure items in order to pass the information to an external processor.
val drop_ppx_context_str :
restore:bool ->
Parsetree.structure_item list ->
Parsetree.structure_item listDrop the ocaml.ppx.context attribute from a structure. If restore is true, also restore the associated data in the current process.
val add_ppx_context_sig :
tool_name:string ->
Parsetree.signature_item list ->
Parsetree.signature_item listSame as add_ppx_context_str, but for signatures.
val drop_ppx_context_sig :
restore:bool ->
Parsetree.signature_item list ->
Parsetree.signature_item listSame as drop_ppx_context_str, but for signatures.
Can be used within a ppx preprocessor to know which tool is calling it "ocamlc", "ocamlopt", "ocamldoc", "ocamldep", "ocaml", ...
